We propose time-frequency domain methods for noise estimation and speech enhancement. A speech presence detection method is used to find connected time-frequency regions of speech presence. These regions are used by a noise estimation method and both the speech presence decisions and the noise estimate are used in the speech enhancement method. Different attenuation rules are applied to regions wi
Let v be a vertex with n edges incident to it, such that the n edges partition an infinitesimally small circle C around v into convex pieces. The minimum local convex partition (MLCP) problem asks for two or three out of the n edges that still partition C into convex pieces and that are of minimum total length. We present an optimal algorithm solving the problem in linear time if the edges inciden
Four kitchens, each with a different work load, were used to evaluate the microbiological risk of utilizing blasting granules in a new type of warewash machine. The granules, plastic pellets 3.5 - 3.5 mm, are recirculated together with the dishwater in the machine, and when the dishwater is expelled, the granules remain in the machine until the next day. Samples of soiled dishwater and tap water w
Solvent extraction of phosphoric acid with Alamine 336 and tri-n-octylamine in toluene has been investigated. The activity of phosphoric acid is expressed as a polynomial of ionic strength and Bromley's model for electrolyte solutions is employed for calculation of ionic activity coefficients. Three species R3N (H3P04) n with n = 1, 2 and 3 in the organic phase are taken into account for explanati
Irradiation with ultraviolet light (UV) at 254 nm is effective in inactivating a wide range of human pathogens. In Sweden, a UV dose of 400 J/m2 is often used for the treatment of drinking water. To investigate its effect on virus inactivation, enteric viruses with different genomic organizations were irradiated with three UV doses (400, 600, and 1000 J/m2), after which their viability on cell cul
This paper considers the problem of finding the cost of a quickest path between two points in the Euclidean plane in the presence of a transportation network. A transportation network consists of a planar network where each road (edge) has an individual speed. A traveler may enter and exit the network at any point on the roads. Along any road the traveler moves with a fixed speed depending on the
According to the 6th chapter, section 2(a) of the Children and Parents code, the best interest of the child shall constitute the main consideration in the determination of all questions concerning custody, residence and contact. Part of the assessment of the best interest of the child, given due weight in accordance with the age and maturity of the child, shall be the views of the child in questio
Background: Surviving sudden cardiac arrest often lead to long-term cognitive, emotional, and physical consequences. Although clinical guidelines recommend structured post-cardiac arrest follow-up, such follow-up is often lacking or inconsistent. Tailored digital interventions are scarce but may help address gaps in follow-up resources. The CARDIS trial evaluates the effects on patient-reported ouBackground: Surviving sudden cardiac arrest often lead to long-term cognitive, emotional, and physical consequences.

We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in th

Information on objectively assessed physical activity in elderly people is scarce. The aim of this study was to investigate accelerometer measures in elderly women, and its relation to other indices of physical activity and bone density. A subset of 57 women, all 80 years old, (range 80.0-80.7) of the Malmo OPRA study was equipped with an MTI accelerometer for a period of 5-7 days. A 7-day activit
This study is an extension of previous studies, Hagnell (1991) and Hagnell(1996), where the data used are annual time series for the whole of Sweden during the period 1751-1850 for the crude birth rate, the death rate for ages 20-50 years, the crude marriage rate and an index of the real wages. The aim of the study of Hagnell (1991) was to investigate the relationships between ferility, adult mort
Background: Low-level processing and normalization of microarray data are most important steps in microarray analysis, which have profound impact on downstream analysis. Multiple methods have been suggested to date, but it is not clear which is the best. It is therefore important to further study the different normalization methods in detail and the nature of microarray data in general. Results: A
